Patent GB-481834-A (GB)
Title: Improvements in or relating to valve circuit arrangements for limiting peak voltages
IPC: H03G11/00
Filed: 1937-05-07
Abstract: 481,834. Transmission systems. STANDARD TELEPHONES & CABLES, Ltd. May 7, 1937, No. 13101. Convention date, June 30, 1936. [Class 40 (iv)] [Also in Groups XL and XXXV] An arrangement for limiting voltage peaks comprises a gaseous discharge device 6 having an anode A, cathode K and control electrode CG, the two latter electrodes being connected to opposite sides of the circuit, the electrode potentials being such that a continuous discharge is maintained between A and the cathode K, a lower potential being applied between K and CG so that the impedance between them decreases with increase of said potential. The operation of device 6 depends on the phenomenon of discharge between two electrodes in a gas at low-pressure (e.g. argon at 10 mm.) which produces a region of intense ionization containing positive ions and electrons in approximately equal numbers. A third electrode CG associated with the other two, will, at a slight positive potential relative to the cathode K, itself become an emitter of electrons and therefore a virtual cathode ; when this voltage is increased the impedance of the cathode-control electrode path rises sharply. The characteristic is then substantially flat over a range of voltages up to about 50 volts when the electrode CG becomes virtually an anode, the impedance of the space K-CG falling from about 500,000 ohms to about 100 ohms as shown in Fig. 3. In Fig. 1 the battery B is about 180 volts, and CG is biassed to a normal potential of 30 volts positive to K, namely to the centre of the flattopped curve of Fig. 3. Thus a powerful limiting action is imposed on positive or negative voltage swings exceeding, say, 25 volts.

Title: Improvements in or relating to timed controlling devices for electric switches, valves and the like
IPC: G04F3/02
Filed: 1936-05-08
Abstract: 474,621. Clockwork actuation of switches and valves. PHILIP, J. May 8, 1936, No. 13114. [Class 38 (v)] [Also in Group XXIX] A clockwork device for operating switches or valves comprises a member 30 adapted to be coupled to the switch or valve and which can be turned by a lever 29 against the action of a spring 37 and held in the set position by the engagement of a pin 31 on an arm 27 with a spring-biassed pawl 32. The tuning mechanism comprises a spindle 16 which can be turned by a knob 17 to wind a spring 21 and return slowly due to the engagement of a friction clutch 23 on spindle 16 with a wheel 24 of an escapement train. The time taken for the return movement depends on the angle through which the knob 17 is turned as shown by a pointer 19 and a scale on the casing. When the pointer returns to zero, a pin 35 on the clutch part 23 trips the pawl 32 and allows member 30 to return to its original position.
Patent GB-696105-A (GB)
Title: Improvements in the manufacture of polyacetaldehydes
IPC: C08G2/12
Filed: 1951-06-04
Abstract: Acetaldehyde is polymerized in the presence of a peroxide catalyst produced by the reaction of oxygen on acetaldehyde, by freezing the monomer at a rate corresponding to the optimum yield of polymer of the desired molecular weight, the rate being determined from the graph of the yields as a function of the freezing rate.  The peroxide catalyst, which may be paracetic acid, is preferably formed in situ by oxidation of the acetaldehyde by distillation in oxygen, by ultra-violet ray irradiation of the acetaldehyde in the presence of oxygen, or by a combination of these means.  When freezing is complete the mass may be macerated under water to dissolve unpolymerized acetaldehyde.  The polyacetaldehyde produced has a molecular weight, varying inversely as the square root of the catalyst concentration, of between 800,000 and 3,000,000, and may be stabilized by the addition of antioxidants such as hydroquinone and alpha and beta naphthylamines.  The products may be used in paints and varnishes, as adhesives, and as solid fuels.

Abstract: 383,952. Reinforced concrete pipes. BILL•, L., 45, Grande-Rue, Nogent-sur- Marne, Seine, France. May 11, 1931, No. 13954. Convention date, Jan. 7. Addition to 378,932. [Class 99 (ii).] In a method of making reinforced concrete pipes in a machine according to the parent Specification, the concrete lining on which the reinforcement is wound is formed wholly or in part with circumferential grooves so that the longitudinal reinforcing members are tensioned by winding over them a reinforcing wire. The winding of the wire is regulated as in the parent Specification by a tensioning device 4, the carriage of which is weighted at 37<1> and is provided with a roller 36 mounted on a spring arm 37 to relieve the pipe of lateral strain. When the outer layer of cement &c. has been applied, a dry hemp cord 39 is wound on the pipe, the moisture of the cement contracting the cord to compress the material of the pipe, lateral strain being relieved during winding by a travelling support 38. In place of a corrugated pipe, spaced cement rings may be provided on a mandrel, the tube being completed after reinforcing by means of a trowel or cement gun. Alternatively the corrugated effect may be obtained by winding a wire on a plain cement lining before applying the longitudinal members.
